To all whom; it may 007L0677t.'

Be it known jthat l, JAcoB' T, Ons'ro'r'r, a citizen) ofthe United, Statesof America, residing at. Yuba City; in the county of Sutter and State of California have invented certain. new and, useful Improvements in Tractor Cut-Out; Flows; and I'do declare the following-to; be a'clear, full and exact description of the same, reference being'had to the, accompanyii' g drawings and to the characters of reference marked thereon, which form apart of this application;

This invention relates to improvementsin farm implements and particularly to plows to be'drawn'by tractors and adaptable for use in vineyardsand orchards tofplow in line with and between the treesand' vines witheutfinjuring the same. I I f t The principal object ofthe invention is to provide a means for moving the plow beam] and 'plowing'device in and out between "the trees and vines and at the same time hold it rigid against vertical movement thereof I I Another object is to provide a means whereby when the plow share strikes the rootofone offthe trees, thefshare will automa tically tilt upwardly and pass over the root'fwithout uprooting or ruining the tree. Still another object is-to provide a single means both to impart horizontal movementto the plow beam andfyet maintain the rigid vertical'position'of'the same;

,A; furtherobject is to provide the structural partsof the plow at as low a level as possible to prevent the possibility ofthe same striking or injuring the trees or vines as it passes beneath or near the same.

I have also produced a simple and inexpensive deviceand yet onewhich will'be e2;- ceedin'gly effective for the purposes for which it is designed. I

These objects, I accomplish by means of such structureand' relative arrangement of the partsaswill fully' appear' by a perusal of the following specification and claims.

,On' the drawings, similarcharacters of reference indicate corresponding parts in theseveral views.

I

The rear end of theplo'w beam is forked as at 9, to receive therebetweena horizontal beam 10 which is pivoted; to t he fork at the downwardly from this pivotal pointian' integral with the beam 'lOEis a vertic lli bai 11 onthe l'owfer end of; whichi'the' glowing device 12 'is mounted; v The forked portion 930i the plow beam? and the horizontal bar 107therebetwemrare provided with alin'ejd' holes 20; through open endthereof as 7 at 11?, Depending which are adapted topass wooden pins '21 of a strengthjsufilcient to cause the bar 11 to normally retain itsverticalposition while pIQWing bUt breaking when the plow share comes in contact with a thick root underground, in whichcase the barll tilts up? ward and permits the share: to] pass, over the root without cutting the same or tearing it outof the ground;

on the inner face of this vertical; beam ll are strong bearings 13 in which is turn? ably mounted a'rigiclvertical rodll of substantial construction, the same being mount ed on the bar in a manner to prevent vertical movement of either one relative to the other as by means of a cotter pin 14 or the like. i

' Adjacent the beam 2, the rod 14 turns at a right angle and runs parallel to the beam 2, substantially in line with the pivotal conof a bar 19, the end of said'rod at this point being turned down to form a short arm 14, which asses loosely through a ,hole 19 in the enc of. the bar 19, as shown in Fig. 4.

Byreason of such loose connection and the shortness of the arm 14, even when the pins-21 break and the plow beam 10 swings upwardly, no material binding or movement ofthe member 19 takes place, as the plow will only turn through an arc of or less, and thesaid loose connection is suflicient to accommodate this, taken in connection with, the very slight movement which the arm 14 will have. V

It will be noted that with the horizontal movement given to the plow beam by means of the rigid bar attached against vertical movement thereto, the plow beam and share may be moved horizontally without altering the vertical alinement thereof and permitting it to cut to anequal depth in all positions.

Among the most important of my improvements is the feature of the rigid bar .14 lying along the vertical beam 11 and extending thence at right angles but rigidly, as at 14', through the bearings 15; This supports and braces the vertical beam 11 which is subjected to a terrible strain and holds it straight and vertical at all times without any play or spring and prevents bending or breaking of the same. Also the push of the portion 14"v is distributed equally against the full length of the vertical beam 11 which will cause a positive and accurate movement.

In the modified form shown in Fig. 4, the plow beam 7 is made of one piece and moved horizontally by means of a rod 22 r. secured to the same and extending to an arm 18 pro ect1ng from the post 23, which has a hand bar or arm 24 thereon.

The vertical position of the beam '7 is maintained by means of a transverse beam 25 slidably mounted on the beam 1 and riding on rollers 26 thereon, the beam 25 passing over the beam 7* and being swivelly secured thereto by means of a U-clamp 27. Dirt may be kept away from this sliding beam by means of a removable cover 28 positioned thereover.

Adjustment of the furrow wheel in this case is had by means of a lever and ratchet quadrant mechanism 29 from which a rod 30 extends down to a point adjacent the spindle of the wheel 4.

The plowing device may be reversible so as to throw the dirt in one direction or the other.

From the foregoing description it will i be readily seen that I have produced a tractor output plow which may be operated to cut out of a straightline without moving the motive power. The advantages of this will be obvious to" one skilled in the art. The plow. may be [drawn by any, mo-

tions from such detail may be'resorted' to x as do not form a departure from the spirit of the invention, as defined by the appended claims. 7 r
